Abstract

The invention discloses a method for calculating the spraying density of spacer balls, a visual separation element and a preparation method thereof. The method for calculating the spraying density of spacer balls includes: determining the diameter of spacer balls and the structural parameters of cylindrical lenses; according to the diameter of spacer balls and The structural parameters of the cylindrical lens, calculate the width of the effective contact area between the spacer ball and each cylindrical lens. The occupied area; according to the width of the effective contact area and the structural parameters of the cylindrical lens, the spraying density of the spacer ball is calculated. By using the calculation method for calculating the spraying density of spacer balls provided by the present invention, the calculation of the spraying density of spacer balls in a 2D / 3D switchable display device is realized, so that spacer balls of different densities can be sprayed for cylindrical lenses of different structures in the display device , to achieve the technical effect of reducing the production cost of the display and improving the quality of the display.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of liquid crystal display manufacturing, and in particular to a method for calculating the spraying density of spacer balls, a visual separation element and a preparation method thereof. Background technique [0002] In the traditional Thin Film Transistor-Liquid Crystal Display (TFT-LCD) production process, the main function of the ball spacer (Ball Spacer, hereinafter referred to as BS) is to maintain the distance between the upper and lower glass substrates, that is, the thickness of the liquid crystal cell. , to prevent the response characteristics of the liquid crystal from changing due to the uneven control of the thickness of the liquid crystal cell, and the change of the response performance of the liquid crystal will cause the screen display of the display to be blurred, and the poor spread of the spacer balls will change the contrast value and even affect the size of the vi...
